ELECTRIC HEATING DEVICE FOR MIRROR A mirror heating device for securement to a rear coated surface of a mirror for heating a mirror to a temperature exceeding the ambient temperature of the mirror when used in an area where there is water vapour in the air. The device comprises a first conductive strip which is securable adjacent an edge of the rear surface of the mirror. A connection is made to the first conductive strip to apply a d.c. voltage thereto. A second conductive strip is located adjacent an opposed edge of the rear coated surface of the mirror and a ground connection is connected to that second strip. An intermediate resistive conductor element extends between the first and second conductive strips and is in contact therewith to heat the mirror. An electrical insulator extends over the first and second conductive strips and the intermediate resistive conductor to insulate same. |
